To' @ZZ whom it may concern,.-

Be it known that I, JOHN J. SNYDER, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colo-l rado, have invented.v new and useful Improvements in Gas-Generating Gas-Fixtures, of which the following is a specification.

My invention relates to gas-generating gasfixtures, and contemplates the provision of a fixture which is at once simple and inexpensive in construction and efficient and reliable in operation and is calculated to afford a steady light When the temperature is very low, as well as when it is normal and high.

The invention is possessed of many advantag'eous features other than those mentioned and will be fully understood from the following description and claims when taken in conjunction with the accom panying drawings, in Which- Figure 1 is an elevation, partly in section, illustrating my improved fixture. Fig. 2 is an enlarged vertical section of the burner of the fixture. Fig. 3 is a detail section of the burner, taken in a plane at right angles to Fig. 2. Fig. 4 is a transverse section taken in the plane of line 4 4 of Fig. 3. Fig. 5 is a detail perspective view showing the generator and its appurtenances. Fig. 6 is a detail vertical section of the generator. Fig. 7 is a perspective view lof the generator-protector, which has for its purpose to hold cold air away from the generator. Fig. Sis a detail diametrical section of a modification, and Figs. 9 and 10 are elevations of cleaning instruments used in conjunction with the fixture.

Referring by letter to the said drawings, and more particularly to Figs. l to 7 thereof, A is a reservoir for gasolene or other hydro-Y carbon suitable for consumption in my fixture.

B is a burner, and C is a tube which serves to convey hydrocarbon from the reservoir to the burner. The said tube extends through the vertical center of ,the reservoir and the interiors of the two areconnected by a port a in the tube. At about the distance shownbelow the reservoir the tube is made to describe a right-hand curve b, and is then carried laterally and horizontally to the burner B, While above the reservoir said tube is threaded for the connection of a hanger D'.` This hanger is preferably cast in one piece and is carried toward the left from the tube C and is preferably provided with a loop c.l The upper erid or bearing point CZ of the hanger may be a hook, asvs'hown, when an eye e on a Wall or other support is to be engaged,

or it may be an eye when a hook on a support is to be engaged, as desired. The bearing- 6o pointd of the hanger is arranged coincident with the'vertical center of the fixture. :By virtue of this and the arrangement of the reservoir A on tube C and the curve of said tube C the upper portion of the tube and the burner B will always rest in a Vertical position, irrespective of the 'quantity of hydrocarbon contained in the reservoir A, which is an important advantage. .The tube C terminates in a vertical portio'n f, which is let 7o into a threaded port g in the generator E of the burner. 4.

The generator, which constitutes one of the important features of my invention, is cast in one piece, and in the preferred embodiment of the invention is annular in form or other- Wise shaped to afford a central passage g through it, and is provided with a lateral horizontal flange h, and also with a threaded port c', the latterbeing for the connection of a tube 8o j, which is provided with the usual projector lo and valve Z for controlling thesupply of gas to the injector.

In the main or annular portion of the generator a generating-canal F is drilled or other- 8 5 Wise formed, the said canal, which is preferably of an inverted-V shape, connecting at its ends with the ports g land having its middle or apex arranged close to the upper end of the generator,where the hydrocarbon there- 9o .in will be subjected to the white heat of the mantle G, the lower part of which surrounds the generator and is connected to a support Z' rising from the same, as shown. In casting the generator there is sufficientmetal left 9 5 at the outer side of its upper portion (see mi in Fig. 5) to drill the generating canal F i through, the canal being drilled from t' and g and connecting at the apex close to the upper rim of the generator, as shown in Fig. 6. This 10o metal projects slightly, as shown, but does not interfere with the lower portion of the mantle fitting down over the generator.

By this method of construction a generator' is produced in which the generating-canal is brought up in close proximity to the white heat of the mantle and is separated from said mantle by but a minimum amount of metal, and at the same time a generator which is formed in one piece and not in two sections and in which the generating-canal is easily accessible to the cleaning-wire H.

The generator is further provided with two notches m, the same being formed in its upper end at opposite sidesrof the apex or middle of the canal F and having for their purpose to promote the passage of the heat of the incandescent mantle to the said canal F. When the lamp is in operation, the gas escapes through said notches and extends the incandescent heat of the mantle at that point downward to within about one-sixteenth of an inch from the apex of the canal F, thus greatly promoting the heat of the generatingcanal F, which is an important advantage.

The generator is advantageous because of the facility with which it 'may be cleared throughout its length of the sediment deposited through the hydrocarbon, it being simply necessary when lthe generator is to be cleared to disconnect the tubes fj, remove the generator from the burner, invert it, and work an instrument H (see Fig. 9) in the arms of the canal F, and then hold the burner so as to permit the loosened sediment to drop from the canal.

I is the usual wire-gauze diaphragm, which is seated in an inner rabbet at the upper end of the generator E and above the passage g thereof.

J is a tube which is connected to the generator E and is designed to receive gas from the injector 7c and con vcy it to the space within the said generator. This tube is of course arranged a suilicient distance above the injector to permit of a suitable quantity of air being commingled with the gas before it reaches the point of ignition.

K is the jacket of the burner, which is det'aehably connected by screws n to lugs p on the flange hof qhe generator E. This jacket is provided below the generator with an opening q, normally closed by a vertically-sliding door r, the purpose of which opening is to permit of the introduction of an instrument L, such as shown in Fig. 10, to clear the minute aperture of the iujectora when the same is partially or wholly obstructed by sediment. By virtue of this the aperture of the injector may be cleared so quickly that while the light will be extinguished by the insertion of the instrument L the generator E will not have time to cool, and hence when the cleaning is effected the burner may be again lighted by simply holding a match above the chimney, presently described. j

The jacket K is extended about the proportional distance illustrated above the flange 7L of the generator and is provided at its upper end with an inwardly and upwardly directed flange s, which serves, in conjunction with a rim t, mounted on uprights u, rising from the jacket, to hold a chimney L2. The construction described precludes the use of any buta chimney of small diameter, which is advantageous, because it insures a swift draft and perfect combustion, and hence the maintenance of a stron g and steady light. The draft of air is admitted to the chimney L2 through openings v, formed in the jacket K, adjacent to the upper end thereof, as illustrated.

YVhcn desired, in lieu of providing the jacket K with draft-openings o a perforated gallery L may be employed to supply air to the chimney and support said chimney, the said gallery being removably held on the jacket by frictional contact. When the gallery L is employed, the jacket does not cxtend so far up as in Fig. 2, and in all cases the lower end of the chimney is but a vely slight distance below the incandescent heat.

As a result of this the chimney is uniformly 9o heated from top to bottom and is not liable to break, whichrenders the employment ot` the advantageous small chimney practical. As will be readily observed, the jacket alone or in conjunction with the gallery L' constitutes a burner-casing.

In order to prevent the current of air entering through the apertures e' from cooling the generator, and thereby retardin g the generation of gas and diminishing the light, I provide a protector M, the purpose of which is to hold such airaway from the generator without interfering with its passage to the mantle. This protector M is preferably in the form of a ring, which is split, as shown, so as to accommodate itself tothe mantle-support l', and is placed around the main portion of the generator and held at the proper distance therefrom by suitable lugs w, formed integral with the generator.

Many of the so-called lower-generator"7 fixtures are efficient and afford a good light when the temperature is normal or high; but when the temperature is low the air entering the chimney to support combustion acts against and keeps the generator cool, with the result that the generation of gas is retarded and but a poor unsteady light aiforded.

My improved protector M elfectually prevents the air entering the chimney from acting against the generator, and hence it insures a perfect generation of gas and the pro` duction of a strong and steady light, irrespectivc of the temperature in which the fixture is operated.

The protector M is made in the manner described in order to facilitate its removal when desired, but may be of any other construction calculated to enable it to perform the function stated.

At its lower end the jacket K has a removable foraininated portion N,which serves IIO to enhance the appearance of the burner and hide the same from view. This removable portion, which is normally held by frictional contact on the lower end of the jacket, is provided with a notch .fr for the passage of the valve-stem Z and a slot o for the passage of the tube C. It is designed to be disconnected from the jacket K and moved back out of the way 011 the horizontal portion of the tube C when it is desired for any purpose to gain access to the interior of the burner.

In starting my improved lamp the jacket portion N is moved back on the tube C, as stated, and an alcohol torch or the like is held under the tube j, and when this is done the hydrocarbon as it is expended or converted into vapor or gas passes up the arm of the generating-canal F past its apex and down the canal, where it communicates with the port g. When suflicient gas is thus generated, the valve Z is opened and the fixture lighted by a match or the like held at the top of the chimney. The fixture will remain lighted so long as the valve is left open and the supply of hydrocarbon lasts, the heat of the incandescent mantle serving to maintain the generation of gas in the generator.

Having thus fully described my invention, I claim- 1. In a gas-generating gas-fixture, a generator formed in one piece and provided with a vertical passage and notches in its upper end and also provided with a generatingcanal having an intermediate portion of its length disposed adjacent to the upper end of the generator and arrangedl between the notches in said end; in combination with a hydrocarbon-tube and an injector-tube connected with the generator and communicating with the canal thereof, and a mantle surrounding the generator, substantially as specified.
